Thanks.

There are several other headers in <sys> in -current that include sys/param.h:

 	acl.h:#include <sys/param.h>
 	fail.h:#include <sys/param.h>
 	ktr.h:#include <sys/param.h>
 	malloc.h:#include <sys/param.h>
 	pmckern.h:#include <sys/param.h>
 	posix4.h:#include <sys/param.h>
 	procfs.h:#include <sys/param.h>
 	ptrace.h:#include <sys/param.h>
 	tty.h:#include <sys/param.h>

In FreeBSD-[3-5], procfs.h was the only one of these.  posix4.h also had it,
but wasn't in <sys>.
